How to prevent "shackel flip" with leveling jacks?

I recently installed a Ground control 4 point leveling system on my 5th wheel and noticed a slight problem when we first used it. We was at a local campground and when we lifted the camper with the jacks to level it the shackles on the center pivot flipped over and had the front axle jammed. I was finally able to correct this by lowering the rear and lifting the front to get the shackles to flip back over. To stop this from happening again I had to place boards under the wheels, wait this is why I installed the jacks in the first place!

    If you think the roads in Ohio are bad then you must HATE the roads in Michigan at least the ones that are paved. The roads in Ohio are paved not wash board gravel roads that are so prevalent in Michigan and appear without any warning.


    Yeah, like right in the middle of interstates! (Personally observed in July!!)

  • I have the 4 point ground control and in the lippert documentation it does say not to have tires off the ground. This might be the reason. For me the trick to that is once the trailer is unhooked and truck moved away to lower the front end to level then put down the back jacks and hit auto level. This has worked every time.

    X2 My shocks are good for limiting the droop as well as being shocks....

    are you ready for it,,,

    its not me, its the "others" that will be here soon to do the "anti lifting of the trailer" chant


    I was expecting that too. Some would suggest that the frame will end up in a big V by jacking.

  • Install limiting straps on the axles to keep them from drooping too far.
    Maybe, just maybe something could be welded to the shackle or to the pivot to keep it from dropping too far.
    A longer shackle or a longer pivot would prevent this from happening as well; using a longer shackle would lower the trailer ride height by half of the added length (a shackle 2 inches longer would drop the trailer ride height by 1").

    After my thinking while typing all this, I would try for a longer pivot first. This would move cause the shackle to be more vertical with a load on the suspension, and less likely to turn horizontal when an axle droops (or rides over a curb).
